Quick answer: For many U.S. travelers, a travel eSIM is the easiest way to get data in mainland China while keeping a U.S. line available for bank texts. The best choice depends on whether you want the lowest price, unlimited data, hotspot use, or confirmed access to Google/WhatsApp without a separate VPN.
Prices and plans change frequently. The examples below were checked against provider pages on October 11, 2026.

Which China eSIM should you choose?
Best for the lowest cost: Trip.com
Trip.com lists many China eSIM products with both daily-data and total-data options. Its current guide shows an example 500 MB/day plan from $0.49, with larger plans available.
This is a practical choice when:
- price matters most
- you know approximately how much data you use
- you are comfortable comparing several similar products
Because Trip.com sells multiple eSIM products, verify the exact network, data policy, hotspot rules and activation instructions on the specific listing you buy.

Best established eSIM platform: Airalo
Airalo currently offers both fixed-data and unlimited China plans. Its official China guide says traffic is routed outside mainland China, allowing access to services such as Google without a separate VPN.
Current unlimited examples:
- 3 days: $11.50
- 7 days: $27
- 10 days: $35
- 30 days: $69
Airalo says hotspot/tethering is supported as long as the device and network support it.

Best low-cost fixed-data option: Saily
Saily currently lists:
- 1 GB / 7 days: $4.49
- 3 GB / 30 days: $10.99
- 5 GB / 30 days: $15.99
- 10 GB / 30 days: $26.99
- 20 GB / 30 days: $39.99
Saily uses one reusable eSIM, so you can add future destination plans without installing a new eSIM each time. Its China page also recommends setting up the eSIM before the trip.
For access to specific overseas services in mainland China, verify the current China product details before purchasing rather than assuming every travel eSIM routes traffic the same way.

Holafly’s China product currently offers unlimited phone data, with example prices of:
- 3 days: $11.90
- 7 days: $27.50

What matters most when comparing China eSIMs
1. Access to Google, Gmail and WhatsApp
Do not assume every China eSIM behaves identically.
Some international travel eSIMs route traffic outside mainland China. That can allow access to overseas services that may not work through ordinary mainland internet connections.
Read the provider’s current China-specific documentation before buying.
For more detail, see Does an eSIM Work With Google, Gmail and WhatsApp in China?.
2. Data allowance
For maps, translation, Alipay/Weixin Pay, messaging and normal browsing, many travelers do not need unlimited data.
Heavy users should consider more data if they:
- upload large numbers of photos or videos
- stream video
- work remotely
- use a laptop hotspot
3. Hotspot/tethering
Hotspot rules vary by provider and package.
Airalo generally supports tethering when the network/device allows it. Holafly’s current China plan advertises 1 GB/day of shareable hotspot data. For Trip.com and Saily, check the exact product you are buying.
4. Keep your U.S. number active
Most China travel eSIMs are data-focused. Your existing U.S. line can remain useful for:
- bank verification texts
- account recovery
- calls from home
On a dual-SIM phone, set the travel eSIM as your data line while keeping the U.S. line available. Turn off unwanted data roaming on the U.S. line to avoid surprise charges.
5. Install before leaving home
Install the eSIM while you have reliable Wi-Fi and easy access to your carrier account.
Before buying, confirm:
- your phone supports eSIM
- your phone is carrier-unlocked
- the plan covers mainland China
- you know when the validity period starts
- you understand how to select the eSIM as your data line
What I would choose
Budget-first: Trip.com.
Simple fixed-data plan: Saily.
Established eSIM platform with China-specific routing guidance: Airalo.
Heavy-data / unlimited-data preference: Holafly.
There is no universal winner. Pick the plan that matches your trip length, normal data use, hotspot needs and need for overseas-app access.
FAQ
Can I install an eSIM before I fly?
Yes. Install it while you still have reliable Wi-Fi, but follow the provider’s activation instructions so the validity period does not start earlier than intended.
Will a China travel eSIM give me a Chinese number?
Usually not. Most tourist eSIMs are data-focused, so keep your U.S. line available if you need calls, texts or bank verification.
Should I remove my U.S. SIM?
Not necessarily. Dual-SIM phones can often keep both lines available.
Is an eSIM always cheaper than roaming?
No. Compare the full cost with your U.S. carrier’s international plan, especially for short trips.
